From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

systemd is one of the best things that has happened with linux. Instead of random shell scripts that work differently on each distro, now you have a single ini conf file for your service that configures automatic restarts, sandboxing and activation in a easy to use way.
I'm so confused as to why people hate systemd.
They see all the other stuff that gets packaged under the systemd name and assume it's non-optional. While many distributions do, annoyingly, ship the auxiliary packages like resolved by default, they're not required if you just want to use the init system, and honestly they kind of strike me as an attempt to supplement or replace some of the incumbent components of your average distro.
Systemd-resolved can suck my whole grundle, though.
i see you have not tried to configure and debug dynamic split dns setups that are very common in enterprise vpn world.
before systemd-resolved you had to use dnsmasq running on localhost with bunch of shell scripts to reconfigure it when vpn interfaces come and go for split horizon dns to work propperly.
now with systemd-resolved you can easily tell it what dns prefixes are handeled by what dns server and everything is nicely cleaned up after vpn goes down.
